What would be the best way to backport ROM's? I wish to run CHD games such as Firefox, M.A.C.H. 3, Red Earth, and Area 51. I wish to run both Area 51 and Beast Busters using both the Dreamcast light gun and MAME4ALL. Of course, I will also try to run Dark Stalkers and Road Riot 4x4. Speed will not be an issue because I will simply set those games on "difficult" because the slow MAME speed would be cancelled out.
